Remarkable oxygen promotion of the selective reduction of nitric oxide by hydrogen over Au/NaY and Au/ZSM-5 zeolite catalysts

Abstract

A significant enhancement of the selective reduction of nitrogen oxide by H₂ is produced in the presence of oxygen over Au/NaY and Au/ZSM-5 catalysts by forming NO₂ and N₂O₄ intermediates, which are eventually reduced to N₂.
